Is there a way to test a campaign mission
 

Is there an easy way to test a specific mission of a campaign? I am trying to modify a campaign mission and I would like to test it.

To answer my own question (in case someone else is looking to do this) .. Yes .. there is a DevMode (At least with the DotMod installed, which is what I was troubleshooting anyway).

Once you enable Developer Mode in the game options, you have a button on the upper left of the main map screen that lets you choose a campaign mission.
